Ascaris lumbricoides (roundworm) belongs to the nematodes (threadworms) and is a parasite that infects humans and other mammals.
Ascaris lumbricoides infections (ascariasis) often are asymptomatic: cough, fever, tightness in the chest and eosinophilia may occur. In the course of the infection, patients may experience loss of appetite, sickness and dyspepsia.
Transmission mainly occurs via contaminated water and food.
For a successful inactivation of parasites, specific disinfectants effective against parasites are required.
